fully factorise this:
x^2-3x-xy+3y^2

x(x-3)+y(3y-x) is as best I can get

Yh I had that too but she said the answer needs to be a double bracket which is impossible

I got that aswell :s-smilie:

Are you sure you read the question properly? What if the answer is there is no solution? because there is no way you can have both brackets have the same experession, that Y will always be there :holmes:

Agreed no way an AS question could be that complex

Fully factorise doesn't always mean everything has to be in a bracket, it means everything that can go in a bracket has to be in one

But apprently that's wrong :hmmmm2:

@mediaya you need to double check the question, cause it's not possible to have the same expression in both brackets

Although they did make some changes to A levels making it more harder, so this could be the new A levels maths? :s-smilie:

Lol even so an AS student would not be able to do that, but im sure maths hasn't changed their still doing modular c1, c2 and so on

Yeah she either misread the question/typed it wrong here or the answer is there is no solution. I even ran the equation in a factorising program and still get the same thing :holmes:

Yes i read the question properly, they give u an example and ask to do the same for all the others

Yeah, I tried that method - if put what I put earlier then say it's impossible to factorise further you should be OK
